### Linear Equations

A linear equation can be written in the form ax + by = c, where a, b, and c are real numbers. This is called the standard form of the equation.

A linear function can be written in the form f(x) = mx + b where m and b are real numbers.

The graph of a linear equation or linear function is a straight line.

The x coordinate of the point at which the graph crosses the x axis is called the x-intercept. The y-intercept is defined similarly.
